Notes

These packages contain only the kernel module, and depend on the catalyst-utils package. The catalyst-utils package is kernel-independent and provides the libraries and utilities for Xorg, including ATI's own libGL.so.

After installing the package, you'll need to either source /etc/profile or log out, then back in to set up the environment properly.

If you run both kernel26 and kernel26beyond then install both catalyst module packages. They won't conflict with one another.
